Description
Die Erfindung betrifft zunächst ein Doppelkupplungsgetriebe für ein Kraftfahrzeug, insbesondere mit einem Hybridantrieb, mit einer ersten Getriebeeingangswelle und mit einer zweiten Getriebeeingangswelle, wobei die erste Getriebeeingangswelle über eine erste Kupplung und die zweite Getriebeeingangswelle über eine zweite Kupplung mit einem Verbrennungsmotor, insbesondere mit einer Kurbelwelle des Verbrennungsmotors wirksam verbindbar sind, wobei mehrere einlegbare und/oder herausnehmbare Gangstufen vorgesehen sind, wobei die aufeinanderfolgenden Gangstufen unterschiedlichen Getriebeeingangswellen zugeordnet sind, insbesondere die erste, dritte und/oder fünfte Gangstufe der ersten Getriebeeingangswelle und die zweite, vierte und/oder sechste Gangstufe der zweiten Getriebeeingangswelle zugeordnet sind, wobei mindestens eine – erste – Elektromaschine vorgesehen ist und die Elektromaschine als Elektromotor und/oder Generator betreibbar ist, und wobei die Elektromaschine mit einer der Getriebeeingangswellen wirksam drehbar verbindbar ist. Weiterhin betrifft die Erfindung ein Verfahren zur Steuerung des zuvor genannten Getriebes, wobei durch die erste Getriebeeingangswelle und die der ersten Getriebeeingangswelle zugeordneten Gangstufen im wesentlichen ein erstes Teilgetriebe und durch die zweite Getriebeeingangswelle und die der zweiten Getriebeeingangswelle zugeordneten Gangstufen im wesentlichen ein zweites Teilgetriebe gebildet ist.The Invention relates first a dual-clutch transmission for a motor vehicle, in particular with a hybrid drive, with a first transmission input shaft and with a second transmission input shaft, wherein the first transmission input shaft via a first clutch and the second transmission input shaft via a second clutch with an internal combustion engine, in particular with a crankshaft of the Combustion engine can be effectively connected, with several einlegbare and / or removable gear ratios are provided, wherein the successive Gear stages are assigned to different transmission input shafts, in particular the first, third and / or fifth gear stage of the first transmission input shaft and the second, fourth and / or sixth gear stage of the second transmission input shaft are assigned, wherein at least one - provided first - electric machine is and the electric machine as an electric motor and / or generator is operable, and wherein the electric machine with one of the transmission input shafts is effectively rotatably connected.

Im Stand der Technik sind unterschiedlich ausgebildete Getriebe, insbesondere auch mit Hybridantrieben bekannt. Das bisher bekannte grundlegende Prinzip der Hybridantriebe geht dahin, dass zwischen dem Verbrennungsmotor und dem Getriebe eines Kraftfahrzeuges eine als Elektromotor ausgebildete Elektromaschine angeordnet ist. Zwischen dem Verbrennungsmotor und der als Elektromotor ausgebildeten Elektromaschine ist eine Kupplung einerseits und andererseits eine weitere Kupplung zwischen der Elektromaschine und dem Getriebe angeordnet. Damit ist auch ein entsprechender Elektrobetrieb zum Betreiben des Kraftfahrzeuges möglich, wenn bspw. die Kupplung zwischen Verbrennungsmotor und der Elektromaschine geöffnet wird, die Elektromaschine als Elektromotor betrieben wird und das Getriebe dann nur durch den Elektromotor angetrieben wird, wobei die Kupplung zwischen Elektromaschine und Getriebe geschlossen ist.in the State of the art are differently trained transmission, in particular also known with hybrid drives. The previously known basic Principle of hybrid drives is that between the internal combustion engine and the transmission of a motor vehicle designed as an electric motor Electric machine is arranged. Between the combustion engine and the electrical machine designed as an electric motor is a clutch on the one hand and on the other hand another coupling between the electric machine and the transmission arranged. This is also a corresponding electrical operation to operate the motor vehicle possible if, for example, the clutch between the combustion engine and the electric machine is opened, the electric machine is operated as an electric motor and the transmission then only driven by the electric motor, the clutch between electric machine and gearbox is closed.
So sind auch Hybrid-Antriebskonzepte bekannt, wo zwei Elektromaschinen, nämlich eine als Elektromotor ausgebildete Elektromaschine und eine als Generator ausgebildete Elektromaschine zur Realisierung des Antriebes eines Kraftfahrzeuges vorgesehen sind. Hierbei ist vzw. zwischen dem Verbrennungsmotor und dem Getriebe, die als Generator ausgebildete Elektromaschine angeordnet, wobei dann die als Elektromotor ausgebildete Elektromaschine ebenfalls mit dem Getriebe separat verbunden ist, um dieses elektrisch anzutreiben. In einem bestimmten Antriebsmodus, insbesondere bei einem Beschleunigungsvorgang, vzw. auch bei einem Anfahrvorgang kann das Fahrzeug bspw. nur mit dem Elektromotor angetrieben werden, ohne dass der Verbrennungsmotor gestartet werden muss. In einem anderen Fall, bspw. wenn das Fahrzeug bremst, also während des Bremsvorganges kann über die als Generator ausgebildete Elektromaschine entsprechend Energie zurückgewonnen und in den Batterien des Fahrzeugs gespeichert werden. Die gespeicherte Energie kann dann wieder der als Elektromotor ausgebildeten Elektromaschine später zur Verfügung stehen, um das Fahrzeug erneut, insbesondere im Elektro-Fahrbetrieb anzutreiben. Hybrid-Antriebe für Kraftfahrzeuge sind daher insbesondere „Energiespar-Konzepte" zum Einsparen von entsprechendem Kraftstoff, der von dem Verbrennungsmotor benötigt wird.So Hybrid drive concepts are also known where two electric machines, namely a trained as an electric motor electric machine and as Generator trained electric machine for the realization of the drive a motor vehicle are provided. Here is vzw. between the internal combustion engine and the transmission, which are designed as a generator Electric machine arranged, in which case the trained as an electric motor Electric machine is also connected to the gearbox separately, to power this electrically. In a particular drive mode, especially during an acceleration process, vzw. also at one Starting process, the vehicle can, for example, driven only with the electric motor without having to start the combustion engine. In another case, for example, when the vehicle is braking, so during the Braking can over the trained as a generator electric machine according to energy recovered and stored in the batteries of the vehicle. The stored energy can then again designed as an electric motor electric machine later be available, to drive the vehicle again, especially in electric driving. Hybrid drives for motor vehicles are therefore particularly "energy saving concepts" to save corresponding fuel required by the internal combustion engine.

Weiterhin
ist der Fall denkbar, dass das Fahrzeug nur im Elektrobetrieb läuft, also
ohne Verbrennungsmotor VKM betrieben wird. Hierzu ist insbesondere
eine Gangstufe auf einem der Teilgetriebe, insbesondere auf dem
ersten Teilgetriebe eingelegt, wobei die erste Kupplung K1 dann
geöffnet
ist, nämlich
nicht mit dem Verbrennungsmotor VKM verbunden ist. Auf dem zweiten
Teilgetriebe ist dann ebenfalls eine Gangstufe eingelegt, wobei

Wie
bereits oben erwähnt
kann die „Boost-Funktion" durchgeführt werden,

ein entsprechender Gang vorgewählt,
also eine Gangstufe eingelegt, wobei die zweite Kupplung K2 aber
geöffnet
ist. Über das
Planetenradgetriebe
Denkbar
ist auch, dass bei Anfahrvorgängen,
insbesondere Extrem-Beschleunigungen, bei einem Extrem-Beschleunigungsvorgang
dann wie bei den Doppelkupplungsgetrieben üblich jeweils eine Gangstufe
auf jedem Teilgetriebe eingelegt wird. Hier ist dann beim Anfahrvorgang
eine Kupplung, bspw. die erste Kupplung K1 voll geschlossen, während die andere
Kupplung, also K2 mit einem gewollten Schlupf durchrutscht, aber
zusätzlich
entsprechendes Drehmoment vom Verbrennungsmotor VKM an das jeweilige
Teilgetriebe überträgt. Hierdurch
werden die entsprechenden Laufverzahnungen der Teilgetriebe geschont,
weil die Zahnkräfte
in den jeweils eingelegten Gangstufen verringert sind. Bei einem derartigen

Auch
ein Rückwärtsgang
ist nun realisierbar ohne dass ein separates Rückwärts-Zahnrad vorgesehen werden
muss. Das Rückwärtsfahren
kann nun sowohl über
das erste als auch über
das zweite Teilgetriebe realisiert werden, je nach dem, welche Gangstufe
auf welchem Teilgetriebe eingelegt ist. Das Rückwärtsfahren wird dann über eine
entsprechende Drehrichtungsumkehr der jeweiligen Elektromaschine
